Android arcgis 坐标转经纬度

down vote

If you want to convert map point to lat/long you just need to follow this Point mapPoint = mMapView.toMapPoint(point.getX(), point.getY()); //Here point is your MotionEvent point SpatialReference spacRef = SpatialReference.create(4326); //4326 is for Geographic coordinate systems (GCSs) Point ltLn = (Point) GeometryEngine.project(mapPoint,mMapView.getSpatialReference(), spacRef ); //mMapView is your current mapview object ltLn.getY() will give latitude and ltLn.getX() will give longitude

这是esri.SpatialReference函数中的属性，wkid即well-known ID（定义好的） ，4326代表地理坐标系中的GCS_WGS_1984 ，这个可以在arcgis的帮助中查看
